Abstract

is introduced the basic principle of weak periodic signal detection based on chaotic vibration subsystem.The shortcomings of the chaotic Duffing oscillator are presented by analyzingthe traditional detection results and detection principle based on Duffing oscillator, To make up the shortage of Duffing chaotic oscillator,it used multiple auto correlation algorithm to improve the signal to noise ratio of the system.Then the signal Then the output of the multiple autocorrelation algorithm is processed to improved chaotic oscillator system to detect the weak signal of arbitrary targets. Besides,to improve the detection accuracy of the system,the critical threshold of the system is determined by the method of recording the time points of the chaotic state.The detection results of the two methods are compared with the results of the methods, which are based on the detection of the Duffing oscillator and the multiple autocorrelation and the chaotic system,it can proved the feasibility and effectiveness of the two algorithms combined detection system.
